batadv_bla_check_claim(9)

✨ batadv_bla_check_claim — NAME ✨

okay so bestie, buckle up 💅 this page is batadv_bla_check_claim(9) from the Kernel API Manual, and it's literally just one little function asking one big question: is this address claimed or not? that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

bool batadv_bla_check_claim (struct batadv_priv *bat_priv , u8 *addr ,
unsigned short vid );

she returns a bool, she takes three things, and she does not elaborate. main character energy honestly 👑

---

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv holding all the mesh interface information. it's the whole info vault babes, everything about the mesh lives in here 🗂️
• addr — the mac address whose claim status we're checking. yes, that mac address. the one under investigation 🔍
• vid — the VLAN ID. don't skip her, she matters 🫶

---

💜 DESCRIPTION 💜

so what's actually going down: addr gets checked to see if this address is claimed by the local device itself. that's the whole bit. she's checking whether the device is like "yeah that's mine" or whether somebody else out here is claiming it 😭

no cap, that's it. short function, clear purpose, iconic behavior ✨

---

🌈 RETURN 🌈

she gives you back one of two answers, and please read them carefully because they are not symmetrical, bestie:

• true — if bla is disabled, or the mac is claimed by the device ✅
• false — if the device addr is already claimed by another gateway 💀

ngl the false case is the spicy one — another gateway has already planted its flag on this address, so the vibe check has officially failed 😬

the kernel file lives right here: ./net/batman-adv/bridge_loop_avoidance.c — that's where the whole bridge-loop-avoidance saga unfolds (yes, that's what the bla is, the file name literally spoils it 🫣).
